1. All parameters NOT specially mentioned are measured at 24VDC input, rated load and 25of ambient temperature.
2. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets
EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.”

Typical Application Notes
1. 1+1 Redundancy
Using 1 more PSU as the redundant unit
2. 1+N Redundancy: Using more PSUs as the redundant units to increase the reliability
